AUXILIARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 462,925, dated November10, 1891.

Application filed October 13, 1890. Serial No. 367,393. (No model.)

To all 1071,0111, it may concern/.-

Be it known that I, JOHN J. HANLON, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Engine-Governors, whichimprovement is fully set forth in the following specification andaccompanying drawing.

My invention relates to improvements in engine-governors, and has forits object a device which will automatically cause a uniform pressure ofsteam to be maintained in a main engine and at the same time supplymotive power for other mechanisms; and for this purpose it consists ofthe combination of parts hereinafter described.

The figure of the accompanying drawing represents a sectional sideelevation of a gov ernor embodying my invention.

Referring to the drawing, A designates a wheel or cylinder, which ismounted on the shaft B and inclosed in a casing O, the peripheryof saidwheel having pockets 1), which are of such form as to present thegreatest surface to the impact of live steam, said parts A B O D forminga rotary engine. A pipe E leads from a boiler or other suitable sourceof steam-supply to the steam-space F, and a pipe G leads from the sameto an engine H for supplying it with the reduced steam which has passedthrough the rotary engine.

A pipe J leads directly from the steam-sup ply to the engine H, and isprovided with a cock K for opening and closing the same and a valve L,the latter being so connected with the shaft B of the rotary engine asto be operated thereby. For this purpose the following mechanism isemployed: A shaft M, having suitable journal-bearings, is provided witha bevel-wheel N, gearing with a bevelwheel P on a shaft Q, the latterreceiving motion, by means of a belt R, from the shaft 13. Secured tothe shaft M and to a collar S, loosely mounted on said shaft, are theweighted arms T, to which is loosely secured the rising and fallingannulus of the rod U, which annulus is fastened to the valve L, themechanism thus described forming a governor for controlling the saidvalve.

V designates an exhaust-pipe leading from the pipe G to the atmosphereand provided with a cock IV. The pipe G is also provided with a cock Xfor closing the same.

In the pipe E is an automatically-operating valve A, which enters thesteam-chamber space in the rotary engine and prevents action on the rearof the pockets before the same receives the impact of the live steam ontheir front face.

The operation of the device is as follows: The live steam from thesupply-pipeJpasses into the pipeE at the same pressure as in the saidsupply-pipe J, and thence into what forms the rotary engine, the shaft Bof which may be used as a motor for such mechanisms as may be desired.The steam which passes from the rotary engine into the pipe G is soreduced by the same as to be of the required pressure for operating theengine H, the said reduction of pressure being according to the speed ofthe wheel A. \Vhen the steampressure in the pipe G is sufficient toordinarily operate the engine 11, the valve L is nearly closed, so thatlittle or no steam passes throughthe pipe J into the said engine; butwhen an increased steam-pressure is desired in the same the speed of theshaft B is somewhat increased, and the valve L is thereby opened topermit a greater inflow, and consequently pressure, of the steam throughthe pipe J into the said engine H for operating the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. An engine with a main steam-supply pipe leading thereto, a secondengine with a steam-supply pipe leading from the main supply-pipe, andan exhaust-pipe leading to said first engine, and a valve in said mainsteampipe with controlling mechanism connected with a rotary shaft ofthe second engine, said exhaust-pipe of the said second engine having avalve opening to the atmosphere, said parts being combined substantiallyas described.

2. An engine having the steam-supply pipe J, with a cock K and valve L,a second engine with a rotary shaft B, mechanism connecting valve L andshaft B for controlling said valve L, the pipe E, leading from said pipeJ to the second engine, and the exhaust-pipe G, leading from the secondengine to the main e11- gine and having a pipe with cock opening to theatmosphere, said parts being combined substantially as described.
